Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

public virtual Stream GetManifestResourceStream (
	Type type,
	string name
public Stream GetManifestResourceStream (
	Type type, 
	String name
public function GetManifestResourceStream (
	type : Type, 
	name : String
) : Stream
Not applicable.



The type whose namespace is used to scope the manifest resource name.


The case-sensitive name of the manifest resource being requested.

Return Value

A Stream representing the manifest resource; a null reference (Nothing in Visual Basic) if no resources were specified during compilation or if the resource is not visible to the caller.

Exception typeCondition


The name parameter is a null reference (Nothing in Visual Basic).


The name parameter is an empty string ("").


A file that was found could not be loaded.


name was not found.


name is not a valid assembly.

For example, if the full name specified for type is "MyNameSpace.MyClasses" and name is "Net", this method overload searches for a resource named "MyNameSpace.Net".

Resource information is returned only if the resource is visible to the caller, or the caller has ReflectionPermission.


This method returns a null reference (Nothing in Visual Basic) if a private resource in another assembly is accessed and the caller does not have ReflectionPermission with the ReflectionPermissionFlag.MemberAccess flag.

If the assembly manifest lists a resource file, GetManifestResourceStream returns a Stream object even if the resource file cannot be found on disk at the time. If the resource file is not found, passing the resulting Stream object to the ResourceReader constructor causes an ArgumentException.

  • ReflectionPermission  to access a private resource. Associated enumeration: ReflectionPermissionFlag.MemberAccess
  • ReflectionPermission  when invoked late-bound through mechanisms such as Type.InvokeMember. Associated enumeration: ReflectionPermissionFlag.MemberAccess.
